Overview

  • Paracoccus marcusii is a Gram-negative, non-spore-forming, aerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 66%. Paracoccus marcusii is unlikely to be a gut coloniser. (Harker1998)



  • This organism has been recovered from an agar plate (contamination). The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Aerobic and poor growth at 35C suggests this not a gut coloniser.
